bodying my inventionffand l Referring now FigureQisa viewfinside elevation partly herein shown'asecond orIn arm invention n also in the nature of a fountain attachment for a conventional tooth brush, which comprises a body B constructed of elastic rubber, or other suitable resilient material. The body B is of U-shape in cross section to provide spaced apart resilient portions 10 and 11 and a connecting portion 12*,pro-

vided with a longitudinal recess opening to the space between the portions 10 and 11, as shown in Figure 5. A conduit 21 in the form of a length of flexible rubber tubing is adapted to be received and clamped in the recess 20 when the body B is applied to-the tooth brush T as shown in Figures sand 5, and the outlet end of the tubing is provided; with a flange 22 which co-acts with the body to prevent withdrawal of the tubing from the recess. The body is applied to the toothbrush by spreading the portions 1Q and 11}. sufficiently to rec ive theattenuated portion 23 of the brush, following which the portions 10? and 11 are released to cause the portions to, co act in gripping the portion 23 and thus-detachably securing the body to the brush with the outlet end of the tubing 21 disposed for the. delivery of a stream of at'erto the, bristles otthe brush to, rinse the mouth in the manner previously described. Y I Referring now to Figures 6. and; 7, I have herein, shown, third term of my invention also in the nature of a fountain. attachment for a conven tional tooth brush. I Thi form of my invention comprises a, tubular. body B in thefo-rmof an annu us of elastic rub ber or. otherfs uitable resilient material; of an internal diameter to, freely receive the handle24 ofa tooth brushT. nconj inction with the body B? I provid t Conduit in the. form of a length of flexible rubber tub ing 25. having at one end a short section 0t hardrubber tubing 26. i

This form, of my invention is applied to the tooth brush T by first inserting the handle 2i through the openingin the. bodyB and then insertingthe section 26 of the tubing 25 through the opening by expanding or. stretching the body, thus causing. the body and the, tubing to be, secured tothe brush with. the outlet end of thesection 26 disposed adjacent the heel end of the brush bristles for the delivery of a stream of, water to the bristles when the tubing is connected to a suitable source of water supply.

Reference will now be had to Figures 8 and 9 wherein is shown a. fourth form of the invention requiring slight modification of a conventional toothbrush which has. its

bristle carrying head 27 provided adjacent tlie heel end of the brush bristles. with a, slot 28 exending. longitudinally of the head;

ot has relatively, enlarged and reduced portions 29 and 30 respectively, the enlarged portion 2.9 freely receiy-ing one end of a, length of flexible. tubing 31 proa the thickness oftthe head 27 so as to dispose the outlet end of the tubing 31 at such angle that when the tubing is connected to a suitable source of water supply, water will be delivered in proximity to the bristles for rinsing-of the oath the manner set forth in, qo nectionwith th fir t form o my: nv tionit 'Alfl q l h @1 5 tou orms f. o nta tooth. bri shlmnbodyingr this invention have be n shown a seriliediti o b u dertead th r s s l -gee an m fica ions may be made therein without departing from thespiritof the invention, and the spirit and scope of the appended claims.

I claim; 1 fountain attachment for brushes comprising a U-shaped body of resilient material providing spaced apart resilient portions adapted to be spread: to receive and grip. the handle of a brush to securethe bodyto t -hehandlethe body. having a duct formed therein and the, duct being provided with an inlet and an outlet disposed for the delivery of water in proximity to'the brush bristles when the bodyis. applied to. the brush, and a conduit CQIi-BBCted. to the body in, communication with the inlet Off the duct 2. A fountain attachment tor brushes comprising aresilient body of U,-form in cross section. providing spaced apart'jaws and a connecting portion co-.a cting; to; receive and grip abrush handle tosecure the body to. theihandle, the body havinga duct extending through One 0t its jaws. and the connecting portion with the outlet of the duct disposed; for the delivery of; waterin proximity to, the. brush, bristles. when the body is applied to the brush, and a flexible tubeconnected to the-body in communication with the inlet of theduct;

3. A brush havinga. handle projecting from the bristle carrying head thereof andprovided With av longitudinally extending slot adjacent the bristles, the slot having; relatively enlarged and reduced portions. along insertablethrough the enlarged portion of; the slot for clamping by its reduced; portion when the tubing is. shifted along the. length of the slot into thereduced portion thereof; A brush aving: a h n e pr jec ng from, the bristle carryinghead; thereof and provided with a longitudinallyextending slot, adjacennthe bristles, the slothaying, relits length, and a. length offlexible tubing atively enlarged and reduced portions along its length, anda length of flexible tubing ins'ertable through the enlarged portion of the slot for clamping b its reduced portion when the tubing is shi ted along the length of theslot into the reduced portion thereof, the tubing having an outwardly projecting flange thereon providing a stop for preventing Withdrawal of the tubing from the reduced portion of the slot.

5. A brush having a handle projecting from the bristle carrying head thereof and provided With a slot adjacent the bristles, and a length of flexible tubing, the slot being of decreasing width longitudinally for the clamping of one end a of the tubing against displacement in the smaller end of the slot' to secure the tubing to the brush with the outlet of the tubing disposed for the delivery of Water in proximity to the brush bristles.

6. A fountain attachment for toothbrushes comprising a substantially U-shaped body of elastic rubber defining a connecting portion and a pair of spaced apart portions capable of being spread sufiiciently to receive a toothbrush handle and to grip the latter when said pair of portions are released; and a length of flexible tubing, said connecting portion of the body having a recess opening to the space between said pair of portions to receive the tubing when the pair of portions are spreadapart, and to grip the tubing when the pair of portions are released and are gripping the toothbrush handle, whereby to secure the body to the handle and the tubing to the body. a
